Well according to little idea of my Bitcoin has been designed to be a decentralized and persistent store of value , it's the future is not guaranteed.
Bitcoin could exist indefinitely if:
1 The demand for Bitcoin remains, and people continue to use and accept it.
I'll stop you right there. There's a difference between Bitcoin "existing" and Bitcoin being the mainstream investment that it is today.
Bitcoin "existed" back in 2010 when the price of one Bitcoin was $0.10 and only a few people used it. Hardly anybody had heard of it, but it definitely "existed".
However, there are also potential risks and uncertainties that could impact Bitcoins existence, such as:
1. Regulatory changes or bans in various countries.
Again, Bitcoin "not existing" would be hard for regulators to pull off, but if Trump is elected he could declare that his own coin should be the only one that is legal so he could make himself the richest person in the world and outlaw Bitcoin in the USA, and that would drop the price of Bitcoin by about 95%. But Bitcoin would still "exist".
2. Competition from other cryptocurrency or alternative technologies.
Fun fact: IBM mainframes
still exist. And they are still a multibillion dollar business for IBM. Most people probably think they don't exist anymore because they've never seen or used on, but they are definitely still around.
As for competing architectures, obviously I am biased, but I personally think that the blockchain architecture
will go the way of the IBM mainframe because a much better digital currency architecture
now exists and it will eventually take over.
3. Security threats or 51% attacks on the network.
At 51% attack would almost certainly try to take over Bitcoin and get the value from it, not destroy the network as such. We discussed in this at length in
another thread, and one key part of the plan would be that the attacker would hold Bitcoin holders hostage in order to take over, not destroy it outright.
4. Loss of public interest or confidence.
That's really just saying the price might go down. It might. Again, it still "exists" if the price goes down.
